This book provides deep insight into the physical quantity known as chemical activity. The author probes deep into classical thermodynamics in Part I, and then into statistical thermodynamics in Part II, to provide the necessary background. The treatment has been streamlined by placing some background material in appendices. Chemical Activity is of interest not only to those in chemical thermodynamics, but also to chemical engineers working with mass transfer and its applications - for example, separation methods.

The Proteins, Volume II: Chemistry, Biological Activity, and Methods, Part A is a nine-chapter text that explores the chemical and biological aspects of proteins. This book starts with a discussion on the occurrence, distribution, and general chemical and biochemical properties of nucleoproteins, enzymes, and respiratory proteins and toxic proteins. The subsequent chapters cover the biological importance, separation, distribution, and antibacterial activity of food proteins, such as milk, egg, and seed proteins. A chapter explores the general concepts of protein metabolism in plants. The final chapter examines the sources and the action of the protein hormones. Biochemists, physiologists, and medical researchers will find this book invaluable.

Chemistry, Biochemistry, and Pharmacological Activity of Prostanoids contains the proceedings of a symposium on the Chemistry and Biochemistry of Prostanoids held at the University of Salford, England on July 10-14, 1978. Separating 29 papers of the symposium as chapters, this book begins with a description of prostanoids in health and disease and recent developments in the synthesis of antisecretory prostaglandins. Other topics discuss synthesis of some novel 11-deoxyprostaglandins; bicycles, tricycles and prostaglandin synthesis; chemical and biological studies on new prostanoids; and isolation and characterization of enzymes involved in prostaglandin biosynthesis. Structure activity relationships of prostaglandins and a biochemical background of caloric restriction therapy of obesity are also explained.

The steroid scaffold continues to be the structural basis of new drugs for a variety of targets and diseases. Indeed, steroids interact with enzymes and receptors in a strikingly specific manner. Chemistry and Biological Activity of Steroids aims to provide an updated overview of recent advances in the medicinal chemistry of steroids. Novel synthetic methods in the steroids field, including steroid biotransformations, new steroids able to tackle steroid receptors, and steroid enzymes with clinical relevance, are critically reviewed in this book. Furthermore, the diverse physiopathological roles of oxysterols and their therapeutic value are also discussed.

The binding of small ligands to biological molecules is central to most aspects of biological function. The past twenty years has seen the development of an increasing armoury of biophysical methods that not only detect such binding, but also provide varying degrees of information about the kinetics, thermodynamics and structural aspects of the process. These methods have received increasing attention with the growth in more rational approaches to drug discovery and design. This book reviews the latest advances in the application of biophysics to the study of ligand binding. It provides a complete overview of current techniques to identify ligands, characterise their binding sites and understand their binding mechanisms. Particular emphasis is given to the combined use of different techniques and their relative strengths and weaknesses. Consistency in the way each technique is described makes it easy for readers to select the most suitable protocol for their research. The introduction explains why some techniques are more suitable than others and emphasizes the possible synergies between them. The following chapters, all written by a specialist in the particular technique, focus on each method individually. The book finishes by describing how several complimentary techniques can be used together for maximum effectiveness. This book is suitable for biomolecular scientists at graduate or post-doctoral level in academia and industry. Biologists and chemists will also find it a useful introduction to the techniques available.

This book is a research monograph summarizing recent advances related to the molecular structure of water and ice, and it is based on the latest spectroscopic data available. A special focus is given to radio- and microwave frequency regions. Within the five interconnected chapters, the author reviews the electromagnetic waves interaction with water, ice, and moist substances, discussing the microscopic mechanisms behind the dielectric responses. Well-established classic views concerning the structure of water and ice are considered along with new approaches related to atomic and molecular dynamics. Particular attention is given to nanofluidics, atmospheric science, and electrochemistry. The mathematical apparatus, based on diverse approaches employed in condensed matter physics, is widely used and allows the reader to quantitatively describe the electrodynamic response of water and ice in both bulk and confined states. This book is intended for a wide audience covering physicists, electrochemists, geophysicists, engineers, biophysicists, and general scientists who work on the electromagnetic radiation interaction with water and moist substances.
